Question
In quality-control applications of hypothesis testing, the null and alternative hypotheses are frequently specified as
Ho: The production process is performing satisfactorily and H₂: The process is performing in an unsatisfactory
manner. Accordingly, a is sometimes referred to as the producer's risk, while ß is called the consumer's risk. An
injection molder produces plastic golf tees with a mean weight of 0.252 ounce. To investigate whether the injection
molder is operating satisfactorily, 40 tees were randomly sampled from the last hour's production. Their weights (in
ounces) are listed in the accompanying table. Complete parts a through g.
